Hello, If you need assistance finding a part please supply the VIN number of your NORTH AMERICAN vehicle AND the part number you are looking for. 

Symptoms:

  • TCC slip
  • TCC surge
  • Overheated fluid, bushings & converter
  • Poor shift quality
  • Harsh Reverse
  • Low lube oil flow
  • Bushing failure

Cause:

Bore wear at the spring end of the valve allows the SLT circuit and regulated converter pressure to cross leak. Bore wear at the balance end of the valve reduces converter and lube flow.

Correction:

Install the Sonnax Secondary Regulator Valve & Spring kit to restore hydraulic integrity to the circuit.
